Mo3-L1b: Parts of a Cell

Mo3-L1b Parts of a Cell

KEY CONCEPTS:
1. How do the parts of a cell enable it to survive?

Vocabulary A-Z

Let us learn some vocabulary

Cytoplasm
Phospholipid
the liquid part of a cell inside the cell membrane;
contains salts and other molecules

Omega-3 Phospholipid

Cytoplasm

Mitochondrion
an organism that breaks down food and releases Cell membrane
energy.
Cell

Some cells have a cell wall—a strong, rigid layer
outside the cell membrane.

Let’s Begin

The Outside of a Cell

The cell membrane is made of lipids and proteins.

Lipids protect the inside of a cell from the external
environment.

Proteins and lipids in the cell membrane transport
substances between the outside of a cell and the
inside of a cell.
